2. Setup

Initial Cleaning:

Before first use, thoroughly wash all parts of the tumbler and lid. Refer to the "Maintenance and Cleaning" section for detailed instructions.

3. Operating Instructions

Filling the Tumbler:

1. Unscrew the lid from the tumbler.
2. Fill the tumbler with your desired beverage. Do not overfill; leave space for the lid.
3. For best results with hot beverages, pre-heat the tumbler with hot water for 5-10 minutes before filling. For cold beverages, pre-chill with cold water.

Sealing and Drinking:

1. Screw the lid back onto the tumbler until it is securely tightened.
2. To ensure a leak-proof seal, verify that the red indicator on the push-button is visible, indicating the lid is closed.
3. To drink, press the push-button in the center of the lid. The red indicator will disappear, and the drinking mechanism will open.
4. The lid allows for 360-degree drinking, meaning you can sip from any side of the rim.
5. After drinking, press the push-button again to close the drinking mechanism and re-engage the leak-proof seal. The red indicator should reappear.

Using the Built-in Tea Hook:

1. Unscrew the lid from the tumbler.
2. Locate the small hook on the underside of the lid.
3. Hang a tea bag string or a loose-leaf infuser onto this hook.
4. Carefully screw the lid back onto the tumbler, ensuring the tea bag/infuser is submerged in the hot water.
5. Once steeping is complete, unscrew the lid to remove the tea bag/infuser.

4. Maintenance and Cleaning

Regular cleaning is essential to maintain the hygiene and performance of your THERMOS tumbler.

Dishwasher Cleaning:

Both the tumbler body and the lid components are designed to be dishwasher safe. Place them on the top rack of your dishwasher for optimal cleaning.

Hand Washing and Lid Disassembly:

For a more thorough clean, especially for the lid, follow these steps:

1. Unscrew the lid from the tumbler.
2. Disassemble the lid components by twisting and pulling apart the various pieces (e.g., the main lid, the push-button mechanism, and any rubber gaskets). Refer to the product video for a visual guide on disassembly.
3. Wash all disassembled parts with warm, soapy water using a soft brush or sponge.
4. Rinse thoroughly to remove all soap residue.
5. Allow all parts to air dry completely before reassembling to prevent moisture buildup.
6. Reassemble the lid by carefully fitting the components back together. Ensure all gaskets are properly seated to maintain the leak-proof seal.

5. Troubleshooting

Common Issues and Solutions:

• Liquid not staying hot/cold: Ensure the lid is securely tightened and the push-button is in the closed (red indicator visible) position. Pre-heating or pre-chilling the tumbler before use can also improve temperature retention.
• Lid leakage: Check that all lid components, especially the rubber gaskets, are correctly assembled and free from damage or debris. Ensure the lid is screwed on tightly and the push-button is fully closed.
• Difficulty pressing the push-button: Ensure the lid is not overtightened. If the button feels sticky, disassemble and thoroughly clean the lid components as described in the "Maintenance and Cleaning" section.
